WebLatent heat is defined as the heat or energy that is absorbed or released during a phase change of a substance. It could either be from a gas to a liquid or liquid to solid and vice versa. Latent heat is related to a heat … WebThe Heat Flow Rate can be defined as the amount of heat that is being transferred in the material as per the unit amount of time. This can be measured through the formula mentioned below-. Q = −k(A l)(ΔT) Q = − k ( A l) ( Δ T) Where, Q= the transferred heat per unit. k = the thermal conductivity. A =the cross-sectional area.
